I used compressed air to freeze the screw heads, had that recommended to me once, it did work the one time I used it but it might have worked without the spray too, I just know it worked the one time I used it.

 

This.

Anti-sieze does wonders for future changes.

 

Can't you just Not use them screws when re-installing rotors?

I plan to do my brakes in the near future... and not use them screws.

 

Yes they are not really needed.

 

I like to use a 3/8ths socket PH3 bit.



With a ratchet I can get plenty of leverage while also pressing the tool towards the rotor so the bit doesn't strip out of the screw head.

If that fails, I drill them out.

 

I really like my Lisle Made in USA hand impact tool which makes removal a snap:

And I guess I'm bucking the trend here, but I keep the screws on. Just the concept of the rotor being loose like that feels weird to me.

Everyone has theories that they're there just to to make the "factory assembly line" easier. Or that they may reduce vibrations. Or may prevent warpage.

But guess what? In lieu of facts from Honda engineers or any auto manufacturer, I don't want to bet on theories. So I keep it stock, and I keep the screws in my rotors in guidance with the factory manual. Takes 30 seconds.

 

phillips head bit might work but it's better to use the right tool for the job imho

 

While you really dont need theses screws, there is a tiny little risk that the brake rotor came loose when you do some work with the wheels removed without theses screws.
With loose brake rotos fine dirt, rust particles ans so on may find their way between the brake rotos and wheel hub, causing run-out of the rotors.
The risk that this happens is small, but be warned.

 

Yeah, the screw is prolly put on to keep rotor on hub, while on assembly line. I reinstall them, just of sake of completeness.

This little kit has always worked for me.

 

The rotor screws also prevent someone from accidentally pushing the brake pistons in.

If you have the wheels off and use the rotor to turn the steering....you can easily put enough pressure on the pad to push the piston in.

I'm sure there are good reasons that Honda put them there. Best to reuse them if you can.
